1. Product Overview
This manual provides instructions for the Omons DeLaval Cow Milking Unit Cluster Bowl Complete, model HCC150C. This component is designed as a spare part for dairy farm milking systems, specifically for DeLaval units. Its primary function is to facilitate efficient milk flow and prevent over-milking through its transparent design and integrated shut-off valve.
The cluster bowl is made of durable plastic and features a transparent bottom, allowing operators to monitor milk flow. It includes a manual shut-off valve that also activates automatically if the cluster is dislodged, enhancing safety and preventing spills.

2. Components
The HCC150C Cluster Bowl Complete is a single integrated unit designed for easy replacement. Key components include:
- Transparent Plastic Bowl: The main body, allowing visual monitoring of milk flow.
- Manual Shut-off Valve: A black component located at the top, enabling manual control and automatic shut-off upon accidental dislodgement.
- Milk Outlet Tube Connection: The clear tube extending from the side, where milk exits the cluster.
- Air Inlet/Pulsation Connection: A smaller black component on the top, typically for vacuum or pulsation lines.

3. Setup and Installation
This cluster bowl is intended as a replacement part. Ensure the milking system is powered off and depressurized before beginning installation.
- Preparation: Disconnect the existing cluster bowl from the milk line and pulsation lines. Ensure all connections are clean and free of debris.
- Attachment to Milk Line: Connect the milk outlet tube of the new HCC150C cluster bowl to the main milk line of your milking system. Ensure a secure and airtight connection to prevent vacuum leaks.
- Pulsation Line Connection: Attach the pulsation line(s) to the appropriate inlets on the cluster bowl. Refer to your specific milking machine's diagram for correct pulsation line routing.
- Liner Installation (if applicable): If liners are not pre-installed, carefully insert them into the cluster bowl openings, ensuring a snug fit.
- System Check: Once installed, visually inspect all connections for proper seating. Power on the milking system and check for any leaks or abnormal operation before use.

4. Operating Instructions
The HCC150C cluster bowl operates as an integral part of your milking system. Its transparent design allows for real-time monitoring of milk flow, which is crucial for preventing over-milking and ensuring udder health.
- Monitoring Milk Flow: Observe the milk passing through the transparent bowl. When milk flow significantly reduces or stops, it indicates the cow is finished milking.
- Manual Shut-off: In case of an emergency or to stop milk flow manually, operate the black shut-off valve located on top of the cluster bowl.
- Automatic Shut-off: The integrated valve is designed to automatically shut off milk flow if the cluster is accidentally kicked off the udder, minimizing milk loss and maintaining vacuum integrity.

5. Maintenance
Regular cleaning and maintenance are essential to ensure the longevity and hygienic operation of the cluster bowl.
- Daily Cleaning: After each milking session, ensure the cluster bowl is thoroughly rinsed with clean water to remove milk residues. Follow your milking system's standard cleaning protocols, which typically involve circulating cleaning solutions.
- Periodic Inspection: Regularly inspect the transparent bowl for cracks, discoloration, or excessive wear. Check the shut-off valve for smooth operation and ensure it seals properly.
- Gasket and Seal Check: Inspect all gaskets and seals for signs of wear or damage. Replace them as necessary to maintain vacuum integrity and prevent leaks.
- Storage: When not in use, store the cluster bowl in a clean, dry place away from direct sunlight and extreme temperatures.
6. Troubleshooting
This section addresses common issues that may arise with the cluster bowl.
Problem | Possible Cause | Solution |
---|---|---|
Reduced Milk Flow | Obstruction in the bowl or lines; worn liners; insufficient vacuum. | Inspect and clean the bowl and lines. Check and replace liners if necessary. Verify vacuum levels of the milking system. |
Milk Leakage | Loose connections; damaged gaskets/seals; cracked bowl. | Tighten all connections. Inspect and replace damaged gaskets or seals. If the bowl is cracked, it must be replaced. |
Valve Malfunction | Debris in valve mechanism; worn valve components. | Clean the valve mechanism thoroughly. If the valve is still not operating correctly, the cluster bowl may need replacement. |
